WH|FFLETREE=HOOK.

SPECIFICATION forming part of Letters Patent No. 347,774, dated August24, 1886.

Application filed July I, 1886. Serial No. 207, 310. (No model.)

To aZZ whom it may concern.-

Be it known that I, PHILANDER B. COOK, of Hastings, in the county ofDakota and State of Minnesota, have invented certain new and usefulImprovements inWVhiffletree-Hooks or Safety Trace-Fasteners, of whichthe following is a full, clear, and exact description.

This invention relates to devices known as whiffletree-hooks, and whichare ordinarily employed for securely holding in place the traces whenattached to the whiffletree. It relates, however, more particularly tothat class of whiflietrce-hooks in which a lever or its equivalent ismade use of to retract or withdraw the bolt commonly used in suchdevices. It is desirable in all such devices that the parts should beeasily and readily manipulated, and at the same time securely and firmlyhold the traces in place without liability of slipping. or becomingdetached from the whiffletree.

I have discovered that by constructing and arranging the parts of awhiffletree-hook in accordance with my invention I am enabled to easilyand quickly secure the traces in or remove them from their positionsupon the whiflietree; also to overcome any liability of their slippingor becoming detached from the same when not desired.

The device, as I propose to make it, will be simple, cheap, and durable,and ornamental, and can be removed and replaced by new ones in case offracture or getting out of order and rendered unfit for further use.

The nature of my invention and the manner in which the same is or may becarried into effect can best be explained and understood by reference tothe accompanying drawings, in which- Figure 1 is a top view with the lidbroken Fig. 2 is a longitudinal central section.

In the accompanying drawings, A is the whiffletree, of ordinaryconstruction; B, the cap or attachment in which my invention resides,which may be made of any suitable materialsueh, for instance, as brass,copper, or the like. It may be secured to the whiflletree in any of thewell-known ways. In the present instance a central tapering bore is,formed in the attachment B, into which fits one end of the whiffletree,and is secured in place thereon by rivets, cement, or the like.

The cap B is mortised or grooved longitudi- Cap B is grooved or cut awayonits sides,

as at (Z 6, about one-half the depth of groove 0. Groove (Z is slightlyinclined at e and straight at f, as shown in the drawings, while groove0 is a semicircle to receive the end of the lever F.

' The bolt E has a groove, formed therein, which registers with groovesd c. Groove g is slightly wider than groove 0 and narrower than (I, andis inclined at h, i, andj, as seen in the drawings.

' The lever F, which is slightly curved, and may be-of any suitablelength, I prefer to make of steel; but it may be made from any othermaterial which will answer the purpose. This lever is fulerumed at It,in groove 0, and passes through grooves g and d, as shown in thedrawings.

I prefer to cover the several working parts with a removable cover orlid, Z, which is secured to the top of the cap B by screws, so that inany case of disorder or breakage it can be readily removed and theinterior of the same inspected and repaired.

The operation of the device is as follows: Assuming that the trace isupon the whiffletree, and the bolt is projected and forced by thehelical spring against the hook 0, thereby securely holding in place thetrace, in order to remove the trace it is necessary to withdraw thebolt. To do this push back the lever F, and it will press against thebolt at the projection 0, formed by inclines h and i, therebywithdrawing the bolt and allowing the trace to be removed from the hookor its place upon the whiffletree, as the case may be. After this hasbeen done, upon removal of pressure from the lever the spring willbecome expanded, thereby causing the projecting of the bolt against thehook c, as usual.

In conclusion, I would state that I. do not restrict myself to thespecial details of construction and arrangement, inasmuch as the samemay be widely varied without departure from my invention.

Having described my improvements, what I claim as new and of my owninvention is as follows:

1. A whifllctree-hook composed of cap B, having grooves G D and (Z c,springimpelled bolt E, grooved at g, incline i, and lever F, allarranged and operating substantiallyin the manner and for the purposesset forth.

2. The combination of cap B, having grooves ,O D and d e,spring-impelled bolt E, provided with groove 9, which is inclined at hi, and r5 lever F, arranged and operating substantially as and for thepurposes set forth.

In testimony that I claim the foregoing as my own I have hereto afiixcdmy signature in presence of-two witnesses.

PHILANDER B. COOK.
